Qt application could be minimized only once in Mac

  • Overview:
    The logic to minimize the application using 'window()->setWindowState(Qt::WindowMinimized)' is only working for the first time in Mac. Successive call to the same after maximizing the window does not have any action.

    Steps to Reproduce:
    A Qt application was created with a 'minimizeScreen' button which has the action to minimize the window using a call to "window()->setWindowState(Qt::WindowMinimized)" .

    #include "mainwindow.h"
    #include "ui_mainwindow.h"

    MainWindow::MainWindow(QWidget *parent) :
    ui(new Ui::MainWindow)
    connect(ui->minButton, SIGNAL(clicked()), this, SLOT(minimizeWindow()));

    void MainWindow :: minimizeWindow()

    Actual Results:
    The window minimizes for the first time. Successive call to minimize does not have any action.

    Expected Results:
    The window must be minimized every time when the user presses the 'minimizeScreen' button.

    Build Date & Platform:
    Tried with QT 5.0.2 and QT 5.0.1 . OS : MAC OSX 10.8.3

    Hi and welcome to devnet,

    Since you might have found a bug, you should rather check and maybe report this on the "bug report system":http://bugreports.qt-project.org/issues/

    This forum is user oriented and generally not followed by Qt's developers. Your findings will probably get lost. You can also ask on the interest mailing list.

  • Thank you for the input. I had already raised a defect in https://bugs.webkit.org/show_bug.cgi?id=120005

    Why did you report a Qt bug on the WebKit bug report system ?

  • The issue seems to be related to Webkit. Will it be good to move it to bugreports.qt-project.org ?

    You're only showing Qt code so it's impossible to say whether the problem comes from webkit.

    Can you provide a complete minimal example that shows this behavior ?
